HELP! shell extensions on Vista

i'm having a hard time getting my shell extension to load in Vista. The same extension registers and loads fine on XP, but not Vista. Something must have changed.

I had a go at building and installing the sample extensions from dino E's shell book ... they failed to register ! Vista is disallowing regsvr32 to write the usual shell extension keys out... I'm logged in as Administrator. I have even tried it from a CMD box 'run elevated' - no joy....

ok so how does this work in the new World?

PLEEEASE will someone from the microsoft shell team step in and show me how to register and install a shell extension on Vista 5270.

thanks
